Tank might be air locked or completely plugged in tank, not allowing fuel to flow out of tank. See if taking the fuel cap off makes a difference, and check if the engine is sucking air instead of fuel. The electronic shut off valve would be at the carb end of the fuel line. Does the tank have a screen at the outlet that might be completely plugged? Good luck, Smitty
Suck through the fuel line from the tank and see if you can et a flow
If good, then check you are getting impulses from the impulse line. a damp finger works well.
After that make sure you have the pump plumbed in properly.
The impulse goes to the end, intake is directly under impulse
Fuel exit is one the other side.
Usually there are some arrows cast into the body.
